How do you interpret the slope in a cost function?

Back

The slope indicates how much the total cost increases or decreases with each additional unit purchased.

How can you find the slope from two points on a graph?

Back

The slope can be calculated using the formula (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are the coordinates of the two points.
